" SAFETY-CATCH FOR PINS.

SPZCIFICATION forming part of Letters Patent No.

288,897, dated November 20, 1888,

Application filed July 30, 1883. (No model.)

To all whom it may concern.-

Be it known th at I, Gnonen WJVAsHBURN, a citizen of the United States, residing atVVest New Brighton, in the county of Richmond, in the State of New York, have invented a new and useful Improvementin Safety- Catches for Pins, of which the following is a specification.

seroll-eatch commonly used tics above cited, in common with my safetycatches heretofore patented, but of novel and superior construction, as hereinafter set forth and claimed. a

The objects of this invention are superior simplicity and durability in construction, freedom from separable parts, and superior adaptation of the new safety loek-catch, to be furnished, practically complete, to jewelers, for attachment by them and adjustment to pins of difi'erent makes or proportions.

A sheet of drawings accompanies this specification as part thereof.

Figures 1 and 2 of these drawings are perspective views of a magnified illustrative pin provided with this safety lock-catch, showing the same respectively open or unlocked and closed or locked. Figs. 3 and l are respectively an edge view and a view at right angles to said edge view of the safetycatch detached in the shape in which it is made for sale, and Fig. 5 represents a crosssection of the latter on a larger scale. Fig. 6 is an elevation of the catch end of a different pin, illustrating the adaptation of the safety-catch thereto; and Fig. 7 is a perspective view of another safety-catch, illustrating a modification of this invention.

Like letters of reference indicate corresponding parts in all the figures.

In forming this safety-catch in either of its forms, I take an ordinary scroll-catch, A, and

points of the pins and the pres or wires, B, preferably what I term a double Wire, formed by bending a piece of wire upon itself, so that its respective halves lie parallel with each other, the bend of the wire forming its outer end after the parts are united, andsaidparallel parts thereof proj ecting as bars in a plane parallel with the back of the breastpin, or of its body back plate or bar, B, when the safety-catch is attached to the latter, as shown in Figs. 1 to 5, inclusive. Upon said wire or wires B a keeper-slide, G, is mounted, this slide being composed, in the preferred construction illustrated by Figs. 1 to 6, inclusive, of a pair of sleeve-tubes, t t, Fig. 5, fitted to the respective bars formed by said double wire B. Aknobshot, s, which, together with the solder which attaches it, serves to unite said tubes t ion one side thereof, and to provide for readily working the slide by means of a finger-nail and a band or ring, r, fitted to the point of an average pin-tongue, P, the latter attached diametrically opposite said shot, and serving, like it, in connection with its attaching-solder, to unite said tubes it. The slide, as a whole, is thus rendered compact and strong, while it is very readily and cheaply produced.

Preparatory to attaching the safety-catch to the body back plate or bar, B, the outer end of said wire or wires B is bent, as shown in Figs. 1 and 2. Its extremity, finally, as well as the base of the scroll-catch A, is socurely soldered to said body back plate or bar, B, so as to render the safety-catch a solid fixture, with said slide 0 as its only movable part, and this not separable from the remainder.

Jewelers will be furnished with the safet catch in the shape represented by Figs. 3 to 5, inclusive. In this shape, if the said double wire be used as proposed, all the parts are as inseparable from each other as upon the pin, while the safety-catch is ready to be fitted to the body back plate or bar of any breast-pin, instead of an ordinary scroll-catch or a different safety-catch, and may be used as a substitute for the former, with all its advantages fully preserved, and security superadded, wherever an ordinary scroll-catch alone could be used.

attach perpendicularly to its outer side wire only beyond the place for the scroll-catch, it

is only necessary to rebend said wire or wires 13, as illustrated by Fig. 6, so as to secure at once the requisite length of path for said slide 0 and the requisite proximity to the scrollcatch A of the second solder-joint at the eX- tremity of said wire or wires B.

This safety-catch, in either of its forms, may be used in connection with pin-tongues without stop-hinges, as well as those which are' provided with the latter, and the pin-tongue may be inelastic. When the pin-tongue P is open, as represented in Fig. 1, the slide 0 occupies its retracted position. After the pintongue is catched in customary manner, it is only necessary to move said slide 0 inward in a natural way, in order to cause its hand or ring r to embrace the point of the pin-tongue and securely hold the same within the scroll.- catch A, so as to preclude its accidental escape therefrom or the disengagement of the breastpin without the wearers knowledge. The pin is shown so locked in Fig. 2. The frictional hold of the said wire or wires 13 within said slide 0 retains the latter where it is placed with ample security when the parts are properly fitted; and should the slide become loosened by wear the double-wire construction above set forth, or the use of two or more guide-bars, provides for readily tightening the slide by spreading the bars apart or pressing them together more or lessan operation which the wearer can readily perform in a moment. I

In an inferior modification illustrated by Fig. 7 a single wire or bar, B", is employed as a substitute for said double wire B, in connection with a slide, 0 of correspondingly modified construction. In this case the slide 0 consists of a single tube, t fitted to the wire or bar B together with a shot, 8, and a band or ring, 1, to embrace the pin-tongue. The wire or bar 13 must in this case be angular in cross-section, or otherwise adapted to prevent the slide 0 from turning thereon, which is accomplished, when two or more bars are used, by means of ordinary round wire. The mode of operation of the modification is substantially identical with that of the preferred form illustrated by Figs. 1 to 6, inclusive, and the modified safety-catch is attached in substantially the same way to the body back plate or bar of the breastpin. The escape of the slide 0 from the wire B in the modified safetycatch, before the same is attachedor, in other words, in the shape in which it is shown in Fig. 7 may be prevented by a slight preliminary retaining-bend of the wire, and the slide may be made to work more or less tightly by bending the wire more or less.

geese? My present safety lock-catch, as compared with those previously patented by me as aforesaid, is more simple and capable of being more cheaply manufactured, and the separation of its parts, even in its original or sale shape, (represented by Figs. 3, 4-, 5, and 7,) may be prevented without special provision therefor by the said double-wire construction. There is no liability of any part to get out of order. Its slide is the only movable part, and this is subjected to no strain whatever, and in said preferred form the two bars of each double wire may be pressed together or spread apart to form a spring in and of themselves for taking up wear, so that the slide will continue to work snugly and smoothly. Said double wire, or the wires or bars upon which the slide works, also form, in and of themselves, an .excellent shield for the point of the pin-tongue, and provide for modifying said shield with the utmost facility to suit it to different varieties of work .or different forms and sizes of breastpins, as illustrated by Fig. 6 in comparison with Figs. 1 g

and 2, as hereinbefo're set forth.

Having thus described my said safety-catch for pins, I claim as my invention- 1. In a safety lock-catch for pins, the combination, substantially as herein specified, of an ordinary scrollcatch, a bar or bars attached to the outer side of said scroll-catch and adapted to be attached at their outer extremity to the body back plate or bar of the pin, and a keeperslide fitted to said bar or bars, and provided with a band or ring to embrace the point of the pin-tongue, for covering and securing the latter, in the manner set forth.

2. In combination with the body back plate or bar and ordinary pin-tongue of a breastpin, a safety-catch composed of a scroll-catch adapted to engage with and temporarily retain said pin-tongue, a bar or bars projecting from said scroll-catch and serving to mask the point of the catched pin, and a keeper-slide working upon said bar or bars and provided with a band or ring to embrace and lock said pin-tongue, substantially as herein set forth.

3. The combination, with a scroll-catch, A, of the double wire B, forming parallel bars, and attached at its open end to said scrollcatch, and the slide 0, composed of sleevetubes embracing the respective bars, and a knob-shot and locking band or ring attached to said tubes, and serving, with their attaching-solder, to unite the same, substantially as herein set forth.-
